Heat the olive oil in a large saute pan over medium-low heat, and add the garlic and red pepper flakes (if using).
While the garlic is gently warming up (keep an eye on it to make sure it doesn’t brown), pour the tomatoes into a medium-sized bowl, and squish them to your desired texture.
Add the squished tomatoes to the garlic in the pan.
Add the salt, and stir everything to combine.
Turn the heat to medium-high. Once the tomato mixture starts to bubble, reduce the heat back down to medium-low, and allow the mixture to cook for 10 minutes. Now would be a good time to add fresh basil if you’re using it.
Enjoy it right away, or store it for later. this amount of sauce is enough for 1 lb of pasta.
